10 all u-Izmn it "my concern.

Be it known that l, ALBERT GROSSMANN, a

. citizen of the United States, and a resident ling the speeds thereof.

of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Aniomatically-Controlled Conveyors, of which the following is a specification.

This inventionrelates' to means for propelling conveyers and automatically control- Its object is the production of conveyers in which the velocity of propulsion is automatically controlled by the material conveyed and is inversely proportional to the volume or weight of the said inaierial. r r

In this application my convey-er is shown applied in a cane-mill, to which it is specially applicable; but it is, however, capable of M ing used with various other apparatus.

7 lieretofore com'eyers when used 'with the various forms of rolls, crushers, and the like have been geared thereto, and therefore constant or fixed relations between the speeds of the conveyors and the said rolls and the like have been unavoidable. Conveyors for cane-mills, crushers, and the.like are not charged or loaded with any uniformity, portions of the same carrying little or no material, while other portions are often overloaded, by reason of which the said mills, data, that run at speeds maintaining constant or fixed relations with the speeds of the conveyers are not nnif'ormily fed, the conveyors in these cases being propelled by the driving motors, engines, and the like that run at constant speeds by the interposition of clutches which either compel the conveyors to run at one speed or to he stopped alto: gather. \Vith my improvements ihe speeds of the conveyers are automatically increased when lightly loaded or decreased when over-' loaded, thereby bringing uniform charges to the rolls, and consequently insuring their eilicient operation.

Figure 1 represents an elevation'of acanemill with my automatic conveyor and appurtenances, partly in section, on line a: a: of Fig. 2. Fig. 2 shows a partial plan view of Fig. 1.

Referring to the drawings, the rolls A, with their adjustable bearings, are supported in Appllntlu no incl: 10. mod. Serial 1.. mm. m "up 1 the housing B. Stanchions C extend from the frame D and support one end of the conveyor ,Y and the gearing interposed between thesaid 5 5 conveyor and the driving-engine E, a chute Z connecting the conveyor and the said rolls. The engine-shah F carries a sprocket-wheel F',whii-h is cnnnecled with thesprocket wheel.

ing in journal-mixes ll, carries the said wheel G and a pinion l, which latter meshes with the gear J, supported on the shaft K, turning in journal-boxes K, the said shaft K carryingthc pinion L, that meshes with the gear! on the 'cdnveyer drivingshaft N. Two sprocketwheels N are carried on the driving-shaft to propel the conveyer Y, whichfcompriseu two chains connected by slats. Frames 0 extendfrom the casing Y of the conveyor, 10 and they terminate in journal-boxes P for the shaft Q, which latter supports a swinging frame R,wilh the roller 8 journaled in the free end thereof, constil uting a regulator for controllingihespeed of thedriving-engineE,and' consequently the conveyor Y. The roller 8 is showir's'iih angles 3 projecting from its surface to gri p the material conveyed, and it is evident that the regulator might be couof t he motor without. leparting from the spirit of the invention. it might besiniply a movable cover or shoe bearing on the sugar-cane or other material carried by the-conveyer. All

'a link T, that is pinned to a lever U, which actnates a spindle V, connected to a speedclianging pulley \V, and a pulley W, extending from the latter, is driven by the pulley X on the shaft F of the engine by means of n30 iswlescribed in United States Patents Noe. 681,144 and 681,145, dated August 20, 1901, and it it evident that the movements of the spindle V, which are controlled by the mate- 95 rial carried on the con'veyer, govern the speedchanging pulley, and consequently the speed of the engine; t

i It will be evident that when the sugar-cane or' other material passesjrom the conveyor Y 10:: info the chute Z, leading to the rolls A, the said cane acts on the regulator or roller S, raising it when large quantities are passing and lowering the same when small quantities strncted in various r iystocontrol the speed Ghy meanaol' thechain F. AshaftlL-turm 6o arm R exiendsfrom the frame Rand carries beltconneclion. Thespeedmhanging pulley 7 are conveyed. The movements of the regulator 8 being transmitted to its supportingframe are by means of the linkedconnections communicated to the speed-changer to vary the speed of the engine E to snitthe charge of cane on the conveyer, and consequently secnre'a uniform feed for the rolls.

It is eyident that any suitable means to change the speed of the engine could be used, the said device being controlled by the movements of the regulator S, that is controlled by the material on the conveyor.

Having described my invention, I ciaim '1. The combinatibn of a conveyor, an engine driving the conveyor, speed-regulating means connected up between the conveyor and the engine, the said means being controlled by the charges of material carried by the conveyor.

2. The combination of a oonveyer, an engine driving the conveyer, a regulator with the conveyor and bearing on the material conveyed,connections between't'he said regulator and the said engine. v

3. The combination of a conveyer, an en- :5 gine driving the convey'er, a speed-changing device connected up with the engine, a regnlater actuated by the material on the conveyer, connections between the regulator and speed-changing device. 3o

4. The combination of a conveyer, an engine driving the conveyor, journal-boxes adjacent to the conveyor, a frame swinging in the said journal-boxes, a roller jonrnaled'to the free end of the swinging frame, connec- 35 tiens between the swinging frame and the engine.
